They are finally reccommending realistic motor choices for this kit with the E30-4 and the E12-4.
They should completely drop the D12-3 from the list...unless there is zero wind and one wants a lame-O flight it is useless.
The 24mm SU F32-4 is a great motor for this kit.

Yes, there is such a thing as NORMAL, if you have to ask, you probably aren't !

The description on its page doesn't mention the 3 x 18 mm motor cluster option that earlier releases of the Saturn V kit had. While I wouldn't care to try flying it on three C6 black powder motors, three 18 mm composite D10 or D21 motors should give it a sufficiently energetic--and realistic looking, with multiple exhaust flames--flight profile (albeit with the risk of having a motor fail to ignite at launch, of course).

The most realistic flight profile is the single D12-3. Slow and majestic...but it ends a little soon. 3 C6's kick it off the pad quickly, more like the space shuttle. Just about any composite motor makes the liftoff profile look more like a Nike booster. As for multiple exhaust flames, if you keep the mount at it's stock recessed location, you won't see much flame out of smaller outboards. A10's have about finished their peak thrust by the time the rocket clears the pad.

A10s never entered my considerations, although they (or A3-4Ts) might be just right for the BT-60 size, semi-scale Estes Saturn V; somewhere between three and five 13 mm mini motors should give the semi-scale Saturn V realistic liftoffs. (Today's 3D printing could easily make this 1:242 scale model--including in a Skylab 1 version--available again.) Also:

That's what I was thinking (besides the multiple exhaust flames) regarding the 1:100 scale Saturn V--three 18 mm composite "D" motors, with their greater aggregate "dry weight" (after their propellant is consumed) than a single "E" or "F" motor, should provide slow, realistic liftoffs (three D10 composite motors might be a good match for the Estes Saturn V's weight). (The plastic, RTF Cox Saturn V had that same realistic ascent with two D12-3 motors, which the model needed due to its greater weight.)
